Characteristics and Control of Exhaust Noise of Air Distribution Valve in Pneumatic System

In a pneumatic system, the air intake and exhaust of the cylinder are controlled by an air distribution valve, and the noise generated by the air discharged into the atmosphere through the exhaust port of the distribution valve is often greater than the noise generated by any part of the pneumatic system. And cause serious damage and pollution to the operators and the surrounding environment [2].
